Contractor will build estimated $629M demo facility in Tennessee for engineer-developer Kairos Power—the first and only advanced nuclear reactor that feds have approved for construction

Work is under way on two other contracts for the Chickamauga Lock Replacement Project.

Tennessee Valley Authority will build new 1.5-GW gas-fired power plant in east Tennessee, announcing final decision April 2 to retire the 70-year-old Kingston coal-fired facility, despite EPA concerns.

Project would replace coal-fired facility that spilled millions of gallons of coal ash waste in a river and surrounding area after a 2008 impoundment collapse.

The contract covers work at TVA’s hydroelectric dams but not nuclear power plants.

After years of battle, firm that managed remediation of 2008 TVA power plant coal ash site breach in Tennessee sending waste over 300 acres and costing about $1 billion, agrees to undisclosed monetary deal with up to 200 workers who had sought many millions.

Japanese electric vehicle battery maker Envision AESC's plant will have a 30-GWh capacity and potential to expand up to 40 GWh.

The Tennessee Valley Authority's plan to cap, cover and monitor legacy power plant waste in three states is being challenged in court by environmental opponents.
